(5) Reassembly of bending unit (Figs. 12 and 22)
Mount the Cam Cover [6], Turn Table [5] and Center Plate (A) [3] in the reverse of the disassembly procedure.
Before mounting the Center Plate (A) [3], apply grease (TUFREX 251) to the 18 mm dia. hole of Center Plate
(A) [3] adequately. Check that the hole of the Turn Table [5] and the pin of the Cam [8] are properly adjusted
to ensure smooth movement of Roller (B) [30].
(6) Installation of gears
Apply grease (Nippeko SEP-3A) to the meshing parts of First Pinion (B) [55], Second Pinion [47], Third Pinion
[43] and Final Gear [18], and mount them in the reverse of the disassembly procedure. Apply grease
(TUFREX 251) to the Clutch Spring [52], Collar (A) [53] and the boss of First Gear (B) [51] adequately. Check
that the Sensor Holder Ass'y [23] is mounted and the wiring is completed. Secure the Inner Cover Ass'y [13]
